Paper Abstract

White light interferometry is used to measure distributed polarization coupling in high-birefringence polarization-maintaining fibers (PMFs). When there are multiple intrinsic coupling points (CPs), multiple-order ghost CPs will produce. The quantity of multiple-order coupling modes can be calculated recursively. A graphical method is proposed to distinguish the multiple-order ghost CPs from intrinsic CPs. Overlapping of CPs is affected by the positions of disturbance points. Experiments on two and three disturbance points imposed on PMFs are performed. Experimental results show the positions of multiple-order CPs are agree well with graphical analysis. Additionally, the graphical method can be used to analyze other polarization-sensitive optical devices.
